Intelligent traffic signal control method and system for crossroads of primary and secondary lanes

Abstract

The invention discloses an intelligent traffic signal control method and system for crossroads of primary and secondary lanes. The system comprises a communication module, a signal processing module,vehicle detection units, pedestrian crossing request devices, a power module and a traffic light control system, wherein the pedestrian crossing request devices and the vehicle detection units are connected with the signal processing module which is connected with the communication module; the communication module is connected with the traffic light control system; the power module is used for supplying power to the pedestrian crossing request devices, the vehicle detection units, the signal processing module, the communication module and the traffic light control system. With adoption of theintelligent traffic signal control method and system, states of the traffic lights can be switched effectively according to actual conditions of road vehicles and pedestrians, the problem about passage of the secondary lanes, left turning lanes and pedestrians is solved as required, so that smooth passage of vehicles on the primary lanes is realized and can be improved, and road and vehicle usingefficiency is increased.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic, in particular to an intelligent traffic signal control method and a control system for the intersection of primary and secondary lanes. Background technique [0002] With the continuous expansion of the city scale, the number of motor vehicles has increased rapidly, and the urban traffic congestion has become increasingly serious. Improving traffic management capabilities is a problem that every city must face. [0003] At present, the traffic signal lights on the road are generally controlled by timing, and the red light and the green light are regularly switched. At many intersections, there are no vehicles to pass on the secondary lane or the left-turn lane for a long time, and there are no pedestrians to pass on the sidewalk, but the traffic lights still do not switch between traffic lights according to a fixed time. The road gives the green light transit time. Such a traffic si...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides an intelligent traffic signal control method and a control system for the intersection of primary and secondary lanes, which uses the actual conditions of road vehicles and pedestrians to switch the state of traffic lights, and solves the problems of secondary lanes, left-turn lanes and traffic lights as needed. The problem of personnel traffic, and finally solve the problem of unimpeded vehicles on the main road
